Specification of Letters Patent. 7 Patented Dec, 16, 1919,

Application filed December 12, 1915. Serial No. 67,605.

To all whom it may concern:

Be it known that 1, JAMES J. CASEY, a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Shoe-lvlarking Machines, of which the following is a specification.

This. invention relates to devices for marking the position of buttons, button holes orof both on sheet material such as.

leather or cloth.

It is more particularly intended for mark- 7 button hole fly or it may be used for mark ing both at the same time in the manner indicated by application for patent filed'by me on process for marking shoe uppers July 17, 1913, Ser. No. 779,504, and application for patent filed by me on marking machine for shoe uppers, filed Dec. 19,1913, Ser.

No. 807,691, 1,183,432. H

\Vith my device, I use plurality of spaced markin members, such members being prefe *ablyawls, arranged on a curved line.

The principal purpose of my invention is to provide such means for laterally changing or adjusting its curve that the positions of the marking members may be altered or adjusted longitudinally along said line at will. The spaced marking means: may be made so that the spaces between the marking members can not be and issued May 16, 1916, No.

varied, they may be Slightly movable l0ngitudinally, or in my preferred construction,

, I arrange them so that they may be adjusted longitudinally by means independent of the means for changing the lateraLcurvature. This longitudinal adjusting or spacing means preferably acts simultaneously upon all orsubstantially all of the marking members, and increases or diminishes the distances between them equally.

This invention is distinguished from that shown in application for patent filed by me:

Dec. 18, 1915, Serial No. 67,604 formar'kirig machine, from the fact that a flexible strip and the lateral adjustment of marking means through the medium thereof is an i D o ing 2LCl1fl 61811i3 curve and with part of the essential feature, while in such other application it is not an essential feature.

The lateral adjustment or altering the curve need not be simultaneous for all parts thereof.

I prefer to embody my idea in a device which is removable from a punching machine and I preferably make it invertible so that the button locations of the right shoe may be marked by one face and of the left shoe by the other face. In shoe marking machines, the relative V spacing between the buttons or button holes have been made adjustable and simultaneous'ly adjustable, butI can, with my device in its preferred form, not only change the spacing of the buttons but also the curve which they form. different styles of shoes and its length differs for different sizes.

For determining the shapeof the curve,

which are vertically disposed with reference thereto. 7

Fig. 6 is a detail plan view of a modified construction. Fig. 7 isa detail thereof. Fig. 8 shows another modification. Fig. 9 is a section of Fig. 8

on line 9-9. 10 isstill another modification and Fig. 11 is a Sectional detail thereof on line 1111.

A represents the preferred form of my device as a whole. 20 is the bottom plate and 21 is the topplate. Both are preferably flat of curved cont mr and together with a rigid This curve differs for fingers which are of such thickness at their pivot ends 31 and at their other ends 32 that they are shdable between the top and cot-tom plates in what is ordinarily a horizontal plane. Their ends 3:2 project from the c ncave side of the frame and carry at right angles marking means 33 which project at right angles or vertically therefrom. I prefer to arrange on each finger two awls oppositely disposed so that the device may be used either side up.

Each finger is preferably recessed as shown at 3% and near the end opposite the awls is cut away in such a groove 35 that two oppositely disposed pivotal points are formed.

Through these grooves and between the pivotal points, I pass a flexible curved strlp upon which the fingers will pivot. When the curve of this flexible strip is changed, the marking means which include the fingers 30 and awls 33 thus associated therewith will be moved thereby and will assume and follow the curve of such strip.

As a me is for changing the curvature of the strip member, I provide carriers 41 slidable between the top and bottom plates and each grooved at 42 so as to have two oppositely disposed bearing points one on each side of strip i0. These carriers 41 are each bored and threaded to receive the screw shank of a set screw e3 each of which passes through slot 45 in rigid strip 22 which is part of the frame. Each has an annular, neck at which sets into a slot 45.

Ev turning these set screws 43, the carriers s1 are forced in or out carrying wlth them flexible strip 40 which moves the fingers pivoted thereon and the marking members carried by the fingers as shown in Fig. 3.

I may use, to get the proper spacing, disks 48 similar to carriers ll and similarly grooved at $9 between the pivot ends of bertain adjoining fingers 30, to keep them properly spaced. I prefer to connect adjoining lingers 2-30 by means of links 10 which are shown as pivoted near their opposite ends to adjoining fingers, and I prefer that the opposite ends of some of said links should be at different distances from the pivotal points of said adjoining fingers on flexible strip 40. If the links were pivoted at equal distances from such pivotal points, when one finger was moved on its pivot, all the others would move the same distance, but by changing the pivotal distances, I enabled to so arrange the longitudinal adjustment of the marking means that the distances between adjoining marking members can be simultaneously increased or decreased equally or unequally whether on a straight line or a curve.

In marking the position of buttons on shoes, the position of the lower button is usually taken as the fixed point. I therefore arrange so that the marking awl for this button shall be attached to the finger at one end, and I prefer to attach to the finger at the other end a handle such as 37 by which the spacing between the spaced mar ing means including the fingers, links and awls can be conveniently altered and positioned. Soarranged, the distance movedby the awl associated with the finger which carries handle 37 will be the greatest distance and the distances moved by the other awls associated with the other fingers will be less successively down to the awl carried by the finger at the other end which will move a very small distance. By means of a pin 26 which may be passed through any one of the holes 27 in top plate 21 into a hole 38 in the finger to which handle 37 is attached, I can position the parts and lock them against longitudinal displacement.

To assist in taking up loose motion, I may connect. certain fingers by tension springs such as 46 and 47.

This device A as a whole may be attached to or associated with any suitable form of punching machine B such as shown in Fig. 5 whereby it may be caused to move up and down in the process of puncturing or otherwise marking the sheet material upon which it is to be used. It may be attached to the plunger 101 of the punching machine by any suitable means preferably of such a character that it can be attached either side up and with the ends in either direction.

I prefer to fix the end blocks 23 and 2d somewhat in from the ends of the top and bottom plates thus leaving a channel at each end, and I prefer to arrange the plunger 101 with depending clamp members 102 and 103 from which projecting toward each other are tongues 10% and-105 each of a size to fit snugly into an end channel in either direction. When slipped into place, they can be heldthere by means of set screws 106 which tighten the clamps 102 and 103.

In Fig. 6, I show a construction in which the marking means are carried by fingers 50 connected by links 51. Each finger 50 is bifurcated to straddle a collar 52 which has ears 53 to serve as pivots and is fixed by means of a set screw 5st to a flexible strip member 55 which in this case is shown as a wire. 7

Each finger 50 is of sufiicient thickness near its awl carrying end 56 to slide between top plate 57 and bottom plate 58 and the flexible strip 55 is held in position thereby and by tension springs 59 fixed at one end to 55 and at the other end to bottom plate 58. The means for changing the curve of the strip member are shown as eccentrics -60 each of which has a peripheral groove 61 in whichstrlp member sets. Each eccentric is fixed on a pin 62 which passes through the top and bottom plates, and is revoluble. therein and is enlarged at 68 to form a knurled thumb piece for turning. The dis-' tances of the corresponding ends of links 51v curved and the marking means consist of marking members which are shown as awls 71 which pro ect from the top and bottom edges of a flexible strip member 72. Mem-' ber 72 is proximate rigidstrip member and is connected therewith by means of set screws 73. The shank 76 of each of these set screws is threaded and passes through a threaded hole in rigid strip or frame 70.'

Near its end, each set screw 73 passesthrough a longitudinal slot 77 inflexible strip 72 and is kept in place therein by suitable collars one on each side. Each set screw will therefore swivel in the flexible strip and deflect it laterally, thus altering.

tom plate 81 are separated by rigid curved strips 82 and 83 and have end bars 84 and 85. Later-ally slidable between the top and bottom plates are two flexible curved strips 86 and 87 in edgewise relation thereto. Between these fieXible strips 86 and 87 are a plurality of awl blocks 88 which are longitudinally slidable. Each block 88 carries preferably two oppositely disposed awls 89- and between adjoining blocks are compression springs 90. The block adjoining end bar 84- is preferably fixed while set screw 91 which passes through end bar bears against the adjoining awl block 88,. This set screw, together with springs 90, allows longitudinal spacing adjustment as when it is turned in or out, the movement is transmitted to the slidable awl blocks through the springs in a successively decreasing amount. To permit lateral adjustment or change of the curve, I arrange a plurality of vbe'rs .89, block 88, springs 90, etc.

compression springs 92 between rigid strip 88and flexible strip 87 and opposed-to them, I arrange set screws 93 which passthrough rigid strip 82 and bear against flexible strip 86; By screwing in or out these set screws the curve of the marking means may be cl1anged..The top and bottom plates are preferably provided with relatively wide slots 94 and 95 to allow lateral movement of the awls 89 thereinf V In this construction, the flexible curved strip is the strip 86' and the other parallel strip 87 cooperates therewith, while the marking means includes the marking mem- VVith V the construction shown in Figs. 6 and' 7 and also with that shown in Figs.

10' and '1 I can alter the curve almost simultaneously by taking a stiff fiat pattern such as having the desired curve and pressing it up againstthe awlsas shown in Fig. 6 forcing them altogetherto conform to its curve as shown by the dottedlines. I can then look the awls in position by successively turning the eccentrics 60 or the setscrews '93'as the case may be,

, In adjusting for difi'erent'styles and sizes, thelateral adjustment of the curve: may be determi 'ied'by the eye, by a pattern such as 100, or by any other similar means, and after the style 'of the curve is determined, the spacing between the marking membersmay thenbevadjusted to the desired size; or the spacing for the size may be first adjusted and the curve may then be altered for the new style; I 7 r In practice, the end of the button curve which will be near the top of the shoe is nearly straight while the lower middle ion 1 tion' has the greatest curvature. It is therefore desirable that the greatest longitudinal adjustment should come from near the end of the straight portion. This arrangement is shown in Figs. 1, 2 and 3.

It will also be observed that the angles made by the different links with the fingers varies according to whether the adjoining curvature is considerable or slight.

I claim: 7
